Indeed. We have an order relation < in X, and use what mathematicians
call lexicographic order induced in X^n by <.

A question worth asking ourselves, I think, is how good are current
compilers at inlining this stuff. I had an application where thousands
of points (coming from a VRML draw) had to be lexicographically
ordered and analyzed. Given the size of the VRML files, that took
generally a whole night on our machines. I don't dare to imagine what
would have happened by implementing operator<() recursively without
compiler optimization.
